Wet Brag

When someone brags about something he thinks is great but is actually lame and that fact that he's bragging about it makes it worse and makes you wonder what he does when he's alone.

Friend 1: Did you hear? Blake's been bragging he collected all the My Little Pony happy meal toys
Friend 2: Really? What a wet brag, I wonder what he does in his free time
Friend 1: Probably writes MLP fanfics
